The scope of this work is to provide an extensive experimental investigation of ferrotoroidicity, the most recently established type of ferroic order that is based on the uniform unit-cell-sized alignment of magnetic whirls. This is achieved by transferring basic spin configurations pertinent for the emergence of toroidal order to mesoscopic length scales. An engineering of and access to the system's magnetic degrees of freedom is made possible by using nanomagnetic arrays as model systems. The work revealsmicroscopic and macroscopic aspects of toroidally ordered matter beyond the reach of natural materials.

This book provides an overview of the use of toroidal moments. This includes methods of excitation, numerical analysis, and experimental measurements of associating structures. Special emphasis is placed on understanding the fundamental physics, characteristics, and real-world applications of toroidal multipoles. This book also covers a variety of both planar and 3D meta-atom and metamolecule schemes capable to sustain toroidal moments across a wide range of spectrum. It discusses the implementation of innovative approaches, for exploring the spectral features and excitation methodologies, predicting the properties of the correlating metasystems in their excited states. An applicable text for undergraduate, graduate, and postgraduate students, this book is also of interest to researchers, theorizers, and experimentalists working in optical physics, photonics, and nanotechnology.

This textbook bridges the gap between university courses on electrodynamics and the knowledge needed to successfully address the problem of electrodynamics of metamaterials. It appeals to both experimentalists and theoreticians who are interested in the physical basics of metamaterials and plasmonics. Focusing on qualitative fundamental treatment as opposed to quantitative numerical treatment, it covers the phenomena of artificial magnetization at high frequencies, and discusses homogenization procedures and the basics of quantum dynamics in detail. By considering different phenomena it creates a self-consistent qualitative picture to explain most observable phenomena. This allows readers to develop a better understanding of the concepts, and helps to create a conceptual approach, which is especially important in educational contexts. This clearly written book includes problems and solutions for each chapter, which can be used for seminars and homework, as well as qualitative models that are helpful to students.

This book focuses on the use of novel electron microscopy techniques to further our understanding of the physics behind electron–light interactions. It introduces and discusses the methodologies for advancing the field of electron microscopy towards a better control of electron dynamics with significantly improved temporal resolutions, and explores the burgeoning field of nanooptics – the physics of light–matter interaction at the nanoscale – whose practical applications transcend numerous fields such as energy conversion, control of chemical reactions, optically induced phase transitions, quantum cryptography, and data processing. In addition to describing analytical and numerical techniques for exploring the theoretical basis of electron–light interactions, the book showcases a number of relevant case studies, such as optical modes in gold tapers probed by electron beams and investigations of optical excitations in the topological insulator Bi2Se3. The experiments featured provide an impetus to develop more relevant theoretical models, benchmark current approximations, and even more characterization tools based on coherent electron–light interactions.

Covering the fruitful combination of nonlinear optics and ferroic materials! Nonlinear Optics on Ferroic Materials features three fields of physics: symmetry; magnetic or electric, long-range (ferroic) order; and nonlinear laser optics. The book begins by introducing the fundamentals of each of field. Next, it discusses how nonlinear optical studies help to reveal properties that are inaccessible with standard characterization techniques. A systematic discussion is also provided of the unique degrees of freedom of the nonlinear-optical probing of ferroics. The final section of the book explores material classes of primary interest in contemporary condensed-matter physics. This includes multiferroics with magnetoelectric correlations and oxide-electronic materials as well as the applications related to the optical properties of ferroic materials. The book concludes with a look toward future developments in using nonlinear optics to study ferroic materials. Reviews original methods and approaches to applications such as oxide-electronic devices, superconductors, and topological insulators Examines how nonlinear optics and ferroics complement each other for the elucidation of materials properties and the development of new devices Serves as a reference for experienced scientists and innovative researchers The use of nonlinear optics for the study of ferroic materials has seen rising interest in recent years, therefore Nonlinear Optics is a prime resource for researchers in this field today. Manfred Fiebig, PhD, is Professor of Multifunctional Ferroic Materials in the Department of Materials at ETH Zurich, Switzerland. He served as head, resp. deputy head of the Department from 2014-2018. His recent honors include election as APS Fellow, an ERC Advanced Investigator Grant and a three-year appointment as Guest Professor at the Japanese research institute RIKEN.

This book consists of chapters written by international experts on various aspects of single molecule toroics (SMTs).The chapters cover a broad range of relevant topics and highlight the latest advances performed in the field. An up-to-date overview of the emerging SMT architectures is presented while particular attention is given to not only the magnetism and relaxation effects involved but also to the respective applications in advanced electronics and memory devices. The role that lanthanides play -especially that of dysprosium- is discussed, while a thorough analysis using theoretical/ab initio calculations is provided. Since SMTs have grown out of single molecule magnetism (SMM), it is an expanding and topical subject and the present book will engender excitement and interest amongst chemists, physicists, theoreticians and materials scientists. The volume will be of great interest to researchers and graduates working on this topic and particularly those involved in lanthanide chemistry, magnetism and theory.

Toroidal Multipole Moments in Classical Electrodynamics

Stefan Nanz investigates the necessity for three multipole families in classical electrodynamics. He shows that by imposing symmetry and parity constraints, it is sufficient to deal with only two multipole families. This implies that the toroidal multipole moments do not represent an independent multipole family, and they only emerge in the long-wavelength limit.
